- Add a suite of new linting rules and the suggestions API, including grouped accessor pairs, no‑constructor‑return, no‑dupe‑else‑if, no‑setter‑return, prefer‑exponentiation, and enhanced camelcase options.
- Fix a wide range of rule reporting and autofix issues such as JSX spread indentation, token location accuracy, multiline comment whitespace, and unexpected autofixes in prefer‑const and other rules.
- Update documentation, deprecate the personal config and the isSpaceBetweenTokens() API, and bump dependencies (optionator, globals) while adding sponsor and funding metadata.
